[AT] Farmall Super C clutch

[Indiana Robinson]

I've wanted a Super C since they first came out new. Maybe someday yet.
Having said that I have never driven one or worked on one so take what I
say with a grain of salt. I do have 6 IH tractors (in various conditions)
and at least 6 other colors so I have a varied experience. Just understand
I may wander astray on specific details.  :-)
Lots of possibilities here... Always begin at the beginning. Quick story...
I remember back when we got our first TV (early 1950's). In a few years it
began acting up and no amount of tin foil. clothes hangers and standing on
one foot helped. A family friend was there one day and he told my father
that "Mine was acting like that and I turned that little screw in this hole
marked "I forget now what it said". So my father got a small insulated
screwdriver and tried turning the screw. The whole TV went totally dead...
The family friend said "Mine did the same damned thing"... They remained
friends but the friendship was strained... True story.
First read all of this thread from Yesterday's Tractors especially about
lubrication. I hope this link is OK.

First check the free travel of the clutch pedal. I don't know what exactly
it calls for but typically about an inch is OK as long as it has some but
not too much because too much keeps the clutch from disengaging completely.
Next I would look in the access hole under the housing (remove all mouse
nest) and look at the fingers on the pressure plate assembly. Some are
adjustable and sometimes one will work loose and get out of both adjustment
and alignment. Also look to see if there is abnormal wear at the contact
points of the fingers. Not lubing the throw-out bearing, "riding" the
clutch or just heavy wear can damage them. Then prop the clutch pedal down
and look (maybe with a mirror and light) to see if you can see anyplace
where the clutch friction material may be coming apart and maybe shifting
maybe making a spot where it is too thick to release fully.
While the pedal is held down  try to wiggle the transmission shaft to see
if there is excess slop where it enters the pilot bearing. A tiny amount of
movement is probably OK but moving an eighth of an inch is waaay too much.
Use a stick, small bar or big screwdriver to wiggle it but don't use a lot
of force.
Note: I "think" that there are two grease fittings involved internally, one
for the bearing carrier and one for the bearing. I have not encountered
that before but I
think that is what I read. One or two pumps of grease a year should be
plenty. Don't over grease it.
I hope this is of some help.
If push comes to shove I'm in Shelbyville and Diana has a lot of family in
the Hagerstown, Richmond, Cambridge City and Bentonville area. Sadly we
visit many of them in cemeteries these days. We were married in the "Brick
Church" on old road 1 back in 1963. I guess it worked, we are still
married.  :-)
You have probably got this OK but if you hit panic level I could probably
make a drive up that way at some point.
Second Note: I bought an LED lighted endoscope that attaches to my smart
phone. I got it from Amazon for about $14 and it works great for looking in
small places. Will fit in about any spark plug hole.
